CARBURETER.

SPECIFICATION forming part of Letters Patent No. 622,489, dated April 4,1.899. Application filed J'uly 19, 1897. Serial No. 645,132. (Nomodel.)l

To all whom t may concern/.-

Be it known that I, Lnonmns L. KELLY, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Oarbureting Apparatus,of which the following is a specification.

My invention relates to an apparatus for the manufacture ofilluminatinggas from volatile oils, and is especially adapted tocarbureters which employ numerous pipes connected together in series,which contain the oil and through which the air or lgas to be carburetedis also passed to commingle with the oil.

My invention consists in a certain novel construction and arrangement oftubes and intermediate chambers in connection with a superposed oil andgas holder, in certain novel means for supplying` oil to the said pipesand for delivering therefrom gas to the said reservoir, in certain novelmeans for commingling more thoroughly the oil and gas in the pipe connecting said intermediate chambers, and in a certain novel construction,combination, and arrangement of parts connected with the air-pipe of thecarbureter for regulating the supply of air ,'thereto in proportion tothe amount of gas generated and the number of burners to be supplied,the combination and.,

arrangements of parts being si1nple,`inexpen sive, and effective for thepurpose stated.

In the accompanying drawings, which will illustrate my invention, Figure1 is an elevation of my improved apparatus with a part of the casing ofthe carbureter broken away to more clearly show the constructionthereof; Fig. 2, an enlarged detail, partly in section, of theair-regulator; Fig. 3, an enlarged section lof the air-regulating valve;Fig.4,an enlarged section detail of the air retarding and distributingair-pipe section; Fig. 5, aplan View of the air-distributing disk; Fig.6, a plan view of the air-retarding disk of the said airpipe section,and Fig. 7 a transverse section of the cap and base of tworadiator-chambers connected together.

The apparatus consists, essentially, in an air-reservoir 1, an air-pump2, and a carbureter 3, suitably connected together by pipesections, theentire apparatus being adapted to be secured to any suitable base oriioor and easily coupled together or taken apart for repairs or forremovalfrom one place to another.

The air-pump 2 is preferably and in the construction shown driven by ahot-air or gas engine 4, having a base 5 and a waterjacket 6, theair-pumps being connected by a pipe 7 to the air-reservoir 1 and thewaterjacket 6 being connected by pipes 9 and 10, leading, respectively,to the lower and upper end of the water-jacket 6 and to a water-box 11,which latter is connected by a pipe '12, leading to the foot, and byapipe 13, leading to the upper part of the outer jacket or cylinder ofthe carburetor. The carbureter is thus kept supplied withl acontinuously-circulating body of water heated to a suitable degree bythe gas or hot-air engine without additional expense or by a lamp 11a,placed below the water-box.

The carbureter-cylinder 3 contains a 'snitable number of sections 14a14h le?, coupled together in series, each section being connected by aseparate pipe 15a 151 15C with a pipe-section 8b, which leads 4from theair-reservoir, the said pipes 15 15b 15c being pro vided with stop-cocks15e 15f 15g, respectively, to control the admission of air to theseveral radiator-sections.

The supply-pipe 15C connects directly with the base of the section 14Cin this instance, and the pipe 15b connects with the cap of the saidsection 14, the air being thus delivered above the pipes of the section14 in this instance, and the.pipe 15a connects with the cap of the saidsection 14", the air being thus delivered above the pipes of the section14:1 and distributed more equally to the lower end of the pipes of thesaid section than would be the caseV were the air-pipe connection madedirectly to the base of said section. The sections let ltb 14C eachconsist of base-castings 14d, caps 14e, and tubes laf, connectedtogether by screwthreads,the cap of each chamber being connected to thebase of the adjacent chamber by an opening lag of suitable size.Theuppermost section 14 has a central pipe 1-7, which passes up throughthe bot` tom .of an oil-supply tank and gas-reservoir 18, connected atits upper end by a flange 1Sa with the underside of the cover of thecarbureter. One or more small apertures 17 a in said pipe allow the oilto pass from the rcs- ICO of the pipe 17 opens freely to the space abovethe oil in the reservoir 18, and a gas-supply pipe 19 leads from thesaid reservoir to the burners. The pipe 17 prevents the air from actingupon the entire body of oil, thus preserving the quality of the oiluntil it enters the carbureter proper. The tubes 14f of the sections areeach fitted at their lower ends with a retarding and distributingair-pipe section 20, which consists of a short metal tube having anexterior thread 20a, adapted to iit a corresponding inner th readof thesaid tubes'lif and provided with a retarding-disk 20h, provided withseveralholes through which the air under pressure can pass, but inlimited quantities, and is thereby retarded and admitted to anintermediate chamber 2Oc of the pipe-section 20, vthe upper end of saidsection and chamber being provided with an air-distributing disk 20d,having numerous small holes 20e therein through which the air must passbefore it can reach the oil within the tubes laf, the disks 20b and 20dbeing preferably connected by a central stem 20f,

as shown in detail in Figs. 4, 5, and 6. The

` air under pressure is first retarded by the disk 2Ob and then iillingthe intermediate chamber 2OC is caused to enter equally over the entirearea of .the disk 20d and pass up through the oil within the tubes 141to commingle completely and thoroughly therewith, the double perforateddisks serving to check and prevent the air from puffing up into thetubes laf in jets which would leak up the sides of the tube and followalong the same to the gas-holder without sufficiently commingling withthe oil to be properly carbureted.v 1

A check-valve 21 in the pipe 7, leading to the air-reservoir, preventsthe air from passing back to the air-pump from the carbureter, and asimilar check-valve 22 at the discharge end of the pipe 8a prevents thegas from flowing back to the air-reservoir after it has been carbureted. A stop-valve 8d in said pipe also serves to completely cut oitor regulate the discharge of air from the reservoir tothe carbureter,and an oscillatory regulator-valve 23 in the air-pipe 8n is cont-rolledin a novel vmanner by aV valve-regulating device, which will quicklyshutoff the air under pressure from the reservoir to the carbureterWhenever the gas-holder within the same is properly charged and thelights are supplied therefrom at the proper andv predetermined pressure.This adjustment is effected with great accuracyv and with quickresponsive action to the variability of pressure within the gas-holderby means of my improved valve-regulatin g mechanism, which consists in acup 24, secured by a pipe-joint 24JL to the air-supply pipe 8, to therim-flange of which is secured a exible diaphragm 24h by means of a ring24, screwed or riveted thereto, the air passing through the joint 24Caand pressing beneath the extended arca of the diaphragm. A rolling plate25, se-

ervoir 18 down to the sections. The upper end I cured adjustably to asleeve 26 by means of a stem 27 and nut 28, rests upon the top surfaceof the diaphragm 24", and a lever 29, pivotally supported at 30 upon abracket 3l, secured to the pipe 8, is connected at its short arm withthe crank-arm 28'L1 'of the air-regulating valve 23, a'weight 32,adjustably secured upon the longer arm of said lever, serving to nicelyadjust the degree of opening of said valve and serving to quickly openand close the same with a very slight movement of the diaphragm and acorresponding slight variation of the pressure of air beneath the same.The jointed connection between the end of the lever 29 and crank-arm ofthe valve is sufficiently loose to allow the short arm of the lever tovibrate the crank with the greatest precision and rapidity to secure anaccurate and sensitive responsive action of said airregulating valve atall times. The weight 32 may be adjusted to suit the quantity of airadmitted, and thus adapt the carbureter to properly supply any requirednumber of burners at any determined degree of pressure. The richness ofthegas is regulated by opening any one of the cocks lf 15g, thus passingthe air through any required number of sections. The temperature of theoil is raised to the degree best suited for completely decarbureting itby means of the water surrounding the sections, which is kept warm andin circulation within the carbureter-casing by means of pipes leading tothe water-jacket around th'e hot-air or gas pump, which compress the airin the air-reservoir, thus providing in one apparatus easily set up ortransported a complete gas-generating machine.

4The oil thus treated may be of the refuse or or When no engine isemployed in connection with the apparatus, the water may be heated inany preferred manner, as by a burner or by any suitable heating deviceplaced under a water-box connected to the Water-jacket of thecarbureter. v

I claim as my invention and desire to secure by Letters Patent- 1. In agas-machine, a carbureter comprising an oute`11 shell or casing, aseries of oil circulating and commingling sections placed one above theother, each section consisting of numerous pipes secured at their endsto chambers, each chamber having an aperture communicating with theaperture of the adjacent chamber, the topl chamber of one of saidsections being secured to the bottom chamber of the adjacent section incombination with a superposed oil and gas holder and a compressed-airreservoir connected with the bottom chamber of the pipe-sections of thesaid carbureter substantially as described.
